Nodule growth and nitrogen fixation of Calopogonium mucunoides L. show low sensitivity to nitrate
It is well established that nitrate is a potent inhibitor of nodulation and nitrogen fixation in legumes. The objective of this study was to demonstrate the relative insensitivity of these processes to nitrate with ...
Nitrate mass balance in agricultural areas of intensive fertilizer application: the North Maresme aquifer system case study (Spain)
(Sociedad Geológica Mexicana, A.C., 2013)
Conjugated linoleic acid is a preferential substrate for fatty acid nitration
(American Society for Biochemistry and Molecular Biology, 2012-12)
The oxidation and nitration of unsaturated fatty acids by oxides of nitrogen yield electrophilic derivatives that can modulate protein function via post-translational protein modifications. The biological mechanisms ...
Rapid and slow modulation of nitrate reductase activity in the red macroalga Gracilaria chilensis (Gracilariales, Rhodophyta): influence of different nitrogen sources
Nitrate is one of the most important stimuli in nitrate reductase (NR) induction, while ammonium is usually an inhibitor. We evaluated the influence of nitrate, ammonium or urea as nitrogen sources on NR activity of the ...
Regioselectivity of the nitration of phenol by acetyl nitrate adsorbed on silica gel
(Pergamon-elsevier Science LtdOxfordInglaterra, 1999)
Construction of a polymeric liquid-membrane ion-selective electrode (ISE)and its application for determination of nitrate in tomatoes
(SOCIEDAD CHILENA DE QUIMICA, 2004-03)
A potentiometric all-solid-state type ion-selective electrode (ISE) for NO3- was constructed and characterized. It is based on a mixture of tetra-decyl-ammonium nitrate (TDAN) as ionophore, di-butyl phthalate (DBP) as ...
A flow-injection spectrophotometric method for nitrate and nitrite,determination through nitric oxide generation
(Elsevier Sci LtdOxfordInglaterra, 2003)
Polarographic determination of nitrate in vegetables
(Elsevier Science BvAmsterdamHolanda, 2000)
Nitrate reductase activity in field-grown pueraria lobata (Kudzu) in southeastern Brazil.
(Pesquisa Agropecuaria Brasileira, Brasilia, v.33, n.12, p.1971-75,dez.1998., 2011)
